Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (salla Allh alaihi wa salam) said,
"He who utters:
`Subhan-Allahi wa bihamdihi
(Allah is free from imperfection and His is the praise)'
one hundred times a day,
his sins will be obliterated even if they are equal to
the extent of the foam of the ocean.''
[Al-Bukhari and Muslim].
The hadith didn`t tell about a certain time this means we can say it any time and Allahu aalam
